Integrating textile materials science and interactive art, intelligent fabrics are evolving from passive surfaces to dynamic systems capable of converting emotional signals into visual expressions. Existing color-changing textiles predominantly utilize photochromic or electrochromic mechanisms, which lack adaptive control in complex environments and demonstrate limited alignment between thermal responses and musical emotion. To address these limitations, this study introduces an emotion-driven thermochromic textile system, termed Emotion-Thermochromic Textile (ETT). ETT features a dual-layer woven structure composed of carbon-fiber conductive yarns and microencapsulated thermochromic coatings, supported by a lightweight emotion-mapping module. In the proposed system, the textile acts as the primary actuator, while the algorithm functions as an auxiliary, translating musical valence-arousal features into thermal control signals. Experimental results indicate that ETT achieves 92.3% emotion-recognition-driven color accuracy, an average response time of 1.8 seconds, and a stable color difference (ΔE) below 3.2 over 50 cycles, with a 26% reduction in energy consumption compared to conventional systems. The findings affirm that material and structural design, rather than computational complexity, govern thermal uniformity and color stability. This research presents a textile-centered framework for emotion-material interaction, offering practical solutions for emotion-responsive textile design in stage performances, wearable technology, and adaptive environments.
